Ensure axial force equal to or greater than that of small screws and bolts! Tapping screws for lightweight alloys.
"Altrax(R)" is a tapping screw for lightweight alloys such as aluminum and magnesium. It has a very high axial force, providing a fastening strength equivalent to or greater than that of bolts (machine screws). There is also minimal reduction in fastening strength due to environmental changes. Regular tapping screws are subjected to carburizing hardening, which raises concerns about brittle fracture; however, this product undergoes quenching and tempering, significantly reducing the risk of brittle fracture. 【Features】 ■ Easy screwing in due to a special tip shape (close to triangular) ■ The 33° thread angle results in a smaller volume for forming the female thread, leading to lower screwing torque ■ An ideally balanced thread profile in relation to the strength of lightweight alloys ■ The cross-section of the screw is perfectly round ■ A large contact area with the mating material allows for stable long-term fastening *For data and material requests, please feel free to contact us through the Yamashina website: http://www.yamashina.ne.jp/

Company information
Established in 1917, during the dawn of mass production of screws in Japan, the company succeeded in producing the first domestic cross-recessed screws in 1949 and cooperated with the government to localize tapping screws in 1954. The company holds data on over 200,000 types of screws and bolts, enabling the high-quality manufacturing of various shaped products. Recently, it has focused on investing in research and development, working on tapping bolts with a diameter of 6mm or more, high-strength aluminum bolts, tapping screws for thin steel plates, and tapping screws for CFRP, which will support the next generation. The company is committed to innovative technological development without being bogged down by history.
